Definition noun A version for enzyme-substrate interaction saying that the enzyme and also the substrate possess particular complementary geometric shapes that fit precisely into one an additional Supplement enzymes are extremely specific. They need to bind come a specific substrate before they can catalyze a chemistry reaction. In ~ present, there room two models, which effort to describe enzyme specificity: (1) lock-and-key model and (2) induced to the right model. In lock-and-key model, the enzyme-substrate interaction suggests that the enzyme and the substrate possess certain complementary geometric shapes that fit exactly into one another. Prefer a key right into a lock, only the exactly size and shape that the substrate (the key) would fit right into the energetic site (the vital hole) of the enzyme (the lock). As for the induced fit model said by Daniel Koshland in 1958, it argues that the energetic site continues to readjust until the substrate is completely bound come the energetic site the the enzyme, at which suggest the final shape and charge is determined. Unlike the lock-and-key model, the induced fit design shows that enzymes are fairly flexible structures. The lock and crucial model theory very first postulated by Emil Fischer in 1894 shows the high specificity the enzymes. However, it does not describe the stabilization that the shift state the the enzymes achieve. Compare:
